Hello, I am looking to measure the diffusion coefficient of a subset of water molecules moving through a pore in a lipid bilayer. In looking at g_msd and the -mol option, the manual states that my index file needs references to molecule numbers rather than atom numbers. I was wondering how I go about this. The help for make_ndx is a bit unclear to me. It seems the selections that I make all end up giving a reference to the atom number. Am I missing something here? How do I get an index file with a reference to the molecule number?
Thanks, Mike Tomasini _______________________________________________ gmx-users mailing list gmx-users@gromacs.org http://www.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/search before posting!
